BREAD-SLICER.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed. August 26, 1909. Serial No. 514,721.

To all whom it may concern:

Be it known that I, VICTOR LARSON, a citi- Zen of the United States,residing at Trimountain, in the county of Houghton and State ofMichigan, have invented certain new and useful Improvements in Bread-Slicers, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to bread slicers and more particularly to adevice of the kind that automaticallyadvances the loaf under the knifethe thickness of one slice with each vertical movement of the knife.

It includes means for holding the bread rigidly in position on the slideunder the knife and means removably inserted in the machine forregulating the thickness of slices.

l Vith this and other objects in view the invention consists in theconstruction and combination of parts as will be hereinafter more fullydescribed in the specification, pointed out in the claim and illustratedin the accompanying drawings, in which- Figure 1 is a broken plan viewof the invention. Fig. 2 is a detail of Fig. 1 taken on line 22. Fig. 3is a bottom plan view of the slide employed. Fig. 1 is a vertical crosssection on line 1-1 of Fig. 1. Fig. 5 is a similar View on line 55 ofFig. 1.

Like reference characters indicate corresponding parts throughout theseveral views.

The numeral 2 represents an oblong casing having a partition 3intermediate its extremities and provided with a vertical slot 4: in thefront end thereof; a similar vertical slot is also provided in theaforesaid partition.

5 represents a knife suspended by swinging arms 6 which arms are hingedas at 7 to the outer and inner surfaces of the front and rear walls,respectively, of the casing. Through this arrangement the knife witharms 6 attached thereto may be manually raised to the position shown indotted lines in Fig. 4 and lowered again thus giving it a verticalmovement in the plane of the easing and through the slots 1 of thepartition and front wall of said casing.

8 is a trough or slideway arranged at right angles to the casing andpositioned between the partition and front end of said casing andprovided with a slide 9 mounted in the side walls thereof; said slide isprovided on its under surface along approximately its longitudinalcenter with raised teeth or serrations 10.

11 is a cross piece running transversely of the trough suitablypositioned between the floor thereof and the slide 9 and having a coilspring 12 secured to one side thereof, said spring in turn being securedat its opposite extremity to a tongue member 13 arranged parallel to thefloor of the trough. Another transverse member 1 1 is arranged in thetrough near its forward end and provided with an aperture 16 throughwhich a cord 15 having one end secured to tongue 13 passes; said cord 15passes over a spool 17 arranged between cross member 11 and the adjacentend of the trough and in a direction toward the front end of the casing,continuing it passes under a spool 18 lying at right angles to the planeof the casing and in the same and upward in a vertical direction throughan aperture in a studding 19 secured to the inner surface of the frontend of the casing and has its extremity secured to the free end of ahinged block 20 lying on the upper extremity of studding 19.

The vertical slot 1 previously spoken of as running through the frontend of the casing is also provided in studding 19. The tongue 13 has itspointed extremity upturned in a manner to engage the serrations arrangedon the under surface of the slide. A pin 21 protruding through one sideof the trough engages the upper surface of the aforesaid tongue by meansof a small metal loop carried thereby; by means of this pin the tonguemay be manually raised or depressed when desired to disengage the teethof the slide while the same is being inserted in the trough. Smallprongs 22 may be arranged on the extremity of the slide remote from theknife to hold the loaf against lateral motion.

Operation: \Vith the slide inserted its full length in the trough theloaf to be cut is placed thereon parallel to the same. The knife is thenmanually raised a suiiicient distance to engage the hinged block carriedon top of studding 19; when this block with cord 15 attached thereto israised the tongue, whose pointed extremity engages serrations 10 of theslide, is drawn forward or toward the knife and the slide is takenforward with it. On the downward stroke of the knife the pressure at thepointed end of the tongue is removed when the spring at its oppositeextremity pulls it back to its normal position and it engages the nexttooth of the slide and is ready for the next upward movement of theknife; thus it will be seen that the bread carried on the upper surfaceof the slide is cut in regular slices, automatically, of a thicknessequal to the distance between the teeth or serrations of said slide. Anumber of slides having varying dis tances between the teeth thereof maybe employed, inserting one with few teeth when large slices are desiredand one with many teeth when thin slices are desired.

hat I claim is- In a bread slicer, a casing having a reciprocating knifetherein, a trough extending through and beyond said casing and at rightangles thereto, a toothed slide arranged within said trough, prongs 22secured to said slide, a tongue arranged in said trough beneath theslide and adapted to engage the teeth thereof to impart motion to theslide, a pin 21 for depressing said tongue when desired, spools suitablypositioned at the junction of the trough and easing, a Vertical studdinghaving an aperture longitudinally therethrough secured to the front wallof the casing, a hinged block secured to the upper surface of saidstudding and adapted for contact with the knife on its upward stroke andconnection between said block and the aforesaid tongue passing over thesaid spools and through the aperture in said studding substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

VICTOR LARSON.
